| frequency modulation n. Abbr. FM The encoding of a carrier wave by variation of its frequency in accordance with an input signal. |
frequency modulation
n
(Electronics & Computer Science / Telecommunications) a method of transmitting information using a radio-frequency carrier wave. The frequency of the carrier wave is varied in accordance with the amplitude and polarity of the input signal, the amplitude of the carrier remaining unchanged Abbreviation FM Compare amplitude modulation
| frequency modulation A method of transmitting signals, especially in radio broadcasting, in which the value of the signal is given by the frequency of a high frequency carrier wave. In FM radio transmission, for example, the signal to be carried is a sound wave, and its increasing and decreasing value is reflected in the increasing and decreasing frequency of a radio frequency carrier wave. Compare amplitude modulation. |
